TO ALL WHOMIT MAY CONCEN: 4 4

Be it known that l, ANDREW J. CnoNK, of the city and county of Peoria,have inrented a new and improved Pad-Tree; and I do hereby declare thatthe following is a full, clear, and exact description of' theconstruction and operation of the seme, reference being had to theaccompanying drawings, making apart of this specification, in nliich IFigure 1 yis a. top iiew of my'improved pad-tree.

Figure 2, a side view.

Figure 3, vertical section of a part of the tree, as indicated by theline M-N i-n g. l..V Likeletters in the dilerent lfigures of thedrawings indicate like parts. The nature ot' my invention consists inthepeculiar construction of' a pad-iron provided with nuts or burs,

und combined with `the bridge by means of screws and the terrets, togive greater strength and soldity to the tree;'also constructing the Dson the ends 'of the'bridge to receive the back-straps, instead of on'the pad-iron, as heretofore, to sustain in -a rncres'ubstnntinl anddurable manner the weightcf the sha-fte.

To enable any one skilled inthe art to make and use my invention, I willproceed toV describeits constructionand operation. f Y

A is the pad-iron, cast with bnrs .or nuts a a, B the bridge or bow, C Cthe Ds for back-straps, D D the terrets, E E the screws. The 1ours 'o'the p adiron are provided with screw-tbreads properly constructed withinthem in the casting. The bridge is made inthe usual form, exceptthattheir ends ure constructed with'Ds The vterrets areas ordinarily. Apadding of leather, F F, is suitably secured around the iron, andcompacted between theburs even with their top edges. (See figs.' 2 eindSuitable springsmay be used in connection with the padding, it' desired.Thle bridge is secured to theirons in the pads by the terrets, andscrews being introduced through holes in the suine and .screwed into the'Durs until the bridge is made fast to the irons, (see igs. 2 and 3,)thusforming a complete and solidfpadftree. :Afa heretofore emarke'd, theDs for the back-straps are generallyconstructod on the ends of thepad-irons, which, bengof a thin plate form, and the manner in whichtheyare connected with the bridge, are not likely to be as strong as onthe ends of the bridge for sustaining theireight of the shafts. The treeis only stationary betweenv the tcrrets, andby a proper adjustment ofthe padding around the irons canvbe generally made to fit the back ofany horse.

Having thus fully described my invention, what I claini therein as new,and desire tofsecure by liietters` Patent, is t 4 u l 1. The pad-iron,as constructed and'combined with the bridge, substantially in'the mannerand for the purpose as herein set forth.

` 2. The bridge, constructed with Ds and combined with the pad-iron,substantially in the manner and for the purpose as herein set term.
